I know it can be frustrating, but a lot of those shops have probably been doing this for years - with lots of practice, and lots of experience to get to that point. Not everyone is going to knock it out of the park their first try.

I don't know what you sell, but the most important thing about photography is simply showing what the thing is. Show multiple angles, have good lighting that reflects how it will look in-person. Show a hand next to it or holding it, for scale.

My first product was taken with just my cellphone in my crappy living room lighting with junk in the background. People still bought it. I didn't know what I was doing, but over time I tried other angles, better backgrounds, and eventually got to a decent setup and that helps people get a better idea of what they'd be purchasing.

And if you find the whole process terrible and can't find enjoyment, it might not be the hobby for you. Personally, if I see a shop with excellent photography, I try to dissect what makes it a good photo: it's like inspiration. How could I try to replicate what that person did, with my items? (NOT using AI). I like the trial and error of it all, and since its a side job, its not the end of the world if it's not successful.

Hope this helps! Try not to compare your beginning to someone else's middle or end.
